Re: [Notion-general] collapse.lua causes segfault since last Debian update

[Arnout E. <no...@bz...>]

Hi Matthieu,

Thanks for the pointer. I've been to run the script and kind of reproduce
the problem: for me notion didn't crash outright but ended up in an
infinite loop - not much better :).

Upon inspection this seems to be a bona fide pointer arithmetic bug that's
been lurking there since before 2005.

I think this should now be fixed on git master HEAD, can you verify it
indeed works for you, too?


Kind regards,

Arnout
